 Title    l,3>5-Tri"ter/-butyl-2,4,6-triisopropyl-3,5-diaza-l-azonia-2,6-dibora- 4-borata[2  
 Abstract    2.0]bicyclohexan, der erste Vertreter der Dewarborazine l,3,5-Tri-terf-butyl-2,4,6-triisopropyl-3,5-diaza-l-azonia-2,6-dibora-4-borata[2.2.0]bicyclohexane, the First D ew ar Borazine The iminoborane /Pr—B = N —rBu (la), metastable at —78 °C, trimerizes to form (/PrBNrBu) 3 (4a) at elevated temperatures. The determination of the molecular and crystal structure reveals 4a to be a Dewar-borazine-type molecule with two short peripheral BN-double-bonds (136 and 138 pm) and an extra-long bridge BN-single-bond (175 pm). The same trimer 4a is formed by addition of la to the diazadiboretidine-type dimer (/PrBNrBu)2, prepared independently. The ethyloboration and the azidoboration of la with BEt3 and Me3SiN3, respectively, and the cyclo-addition of PhN3 to la follow expected patterns.
